That's an *ancient* kernel. :( Any chance you can try it with a newer kernel? Unortunately not, that's our production kernel. > Any other idea about why the scan command it's not properly working ? Another common problem is the clock settings. Are you sure the correct value for board_ref_clock in your board file? Are you talking about "wl->ref_clock = pdata->board_ref_clock;" in the probe ? Which value should I put for 38.4MHz due to the fact that it is an integer parameter ?
